Proportional spool valve for larger volume flows WVBFA10
With its small and compact construction volume, volume flows of up to 200 l/min can be controlled at a pressure of up to 350 bar. Due to its high resolution, high volume flow and low hysteresis, the valve is perfectly suitable for demanding tasks. The nominal flow at a pressure drop of 10 bar is 90 l/min and can be sensitively controlled with a variable solenoid current by the pilot valve. Using suitable control electronics, the response behaviour and the hysteresis can be optimally aligned with the application. The pilot operated valve is used where high volume flows have to be controlled. Due to the large flow range and the high stiffness of the actuation as a result of the pilot control, this valve is suitable for applications where fast acceleration and deceleration processes, high speeds and sensitive motion sequences are required. Applications are found in all sectors where certified explosion protection and a compact and light construction are required. The valve of nominal size NG10 is available as a 4/3- or also as a 4/2-way function with the designation WVBFA10. For the control, electronics mounted directly onto the valve are available (additional designation –M248).
